A Typical Sea-Land Breeze Process in Hainan Island
The automatic weather station data were used to research the evolution and impact factors of tropical island sea breeze convergence in September 2, 2010. Temporal and spatial variation of sea breeze convergence zone, atmospheric background field, physical field and other relevant factors about a typical sea-land breeze process in Hainan Island were diagnostic analyzed. Mesoscale meteorological model WRF was created to simulate the sea-land breeze. The results showed that the subtropical and tropical cyclone were the main synoptic situation which affected the temporal and spatial variation of the sea breeze convergence zone, so there was a significant difference of sea breeze process between both sides of the island. Mesoscale meteorological model WRF simulated the vertical structural features of sea-land breeze circulation and the evolution low of sea breeze convergence zone successfully, resolution of 45 × 15km having a better simulation effect.
